>Which does "radiolocation" mean? Radar or loran/GPS/etc. or both?
LORAN was a system of radionavigation, not radiolocation. Not the same thing.
Radionavigation is just what it says, a system used to help navigate a moving
ship, plane or land vehicle. It was a useful tool for ships trying to navigate
through unfamiliar waterways.
Radiolocation uses single a beacon, transmitting from a fixed point to help
ships, planes or other vehicles arrive at a destination. The 160m radiolocation
beacons were widely used to enable ships and planes to find oil rigs in the
Gulf of Mexico.
GPS has pretty much rendered both systems obsolete. It's a lot cheaper and
easier to use a small handheld or dash-mounted device, linked via satellites,
than to build, operate and maintain a high power MF transmitter and large
antenna system similar to that used by an AM broadcast station.
